10 Claims.

The invention relates to machines for adhesively applying labels andother elements to articles, and has for its object to provide machinesof the indicated class with simple and efiicient means whereby parts ofthe mechanism may be readily adjusted to the most efficient operativecondition and to compensate for wear and the like. The inventioncontemplates further the provision of means whereby the suction head orequivalent transfer device common to machines of the designated typesmay be accurately maintained in the most effective operating adjustment.A further object is to provide simple and efficient means whereby theapplication of adhesive to labels and other elements may be controlledin a predetermined manner. Other more specific objects will appear fromthe description hereinafter, and the features of novelty will be pointedout in the claims.

In the accompanying drawings, which illustrate examples of the inventionwithout defining its limits, Fig. 1 is a fragmentary side elevation,partly in section, of an applying machine with the novel featuresembodied therein; Fig. 2 is a fragmentary side elevation on a somewhatenlarged scale and looking in the opposite direction from Fig. 1; Fig. 3is a plan view of the parts shown in Fig. 2; Fig. 4 is a verticalsection on the line 4--@ of Fig. 2; Fig. 5 is a horizontal section onthe line 5-5 of- Fig. 4; Fig. 6 is a detail section of a guide railincluded in the machine; Fig. 7 is a fragmentary section on the line Ilof Fig. 4; 8 is a section elevation on the line 8-4 of 1; Fig. 9 is adetail I plan view of a novel arrangement for controlling theapplication of adhesive to elements to be adhesively applied toarticles; Fig. 10 is a fragmentary section on the line iii-it of Fig. 9;Fig. 11 is a similar view on the line li-Il of Fig. 9; Fig. 12 is a rearface view of an article subsequent to the application of adhesivethereto, and Fig. 13 is a rear face view of a label or other elementillustrating an example of adhesive application thereto.

The machine selected for the purpose of illustrating the novel featuresincludes a suitable frame i5 on which a container or hopper it of anyconventional type is supported in any convenient manner for the purposeof containing a supply of labels or other elements I! in the form of anyupright supply stack. Generally speaking, the bottom of the container I6is vertically adjustable by means of suitable elevating mechanismautomatically controlled in a manner to periodically restore the upperend of the stack of labels or other elements I! to a predeterminedlevel. For this purpose the machine may include a feeler l3 verticallyslidable in an upright guide l9 and connected by means of a link 20 witha bell-crank lever 2i pivoted at 22 upon the frame [5. The lever 2|carries a roller 23 adapted to be acted on by a cam 24 to verticallyactuate the feeler IS in operative synchronism with the means wherebythe labels or other elements [1 are successively removed from the stackin the container Hi; the cam 24 is carried by a shaft 25 suitablyjournalled in the machine.

In addition the illustrated machine includes adhesive applying meansconsisting of a distributing roll 26 rotatably mounted in the frame [5and dipping into a supply of adhesive in the well-known way; thedistributing roll 26 is located in tangential relation to an adhesive applying roll 27 suitably journalled in the machine in operative relationto the container and stack of labels or other elements I! as shown inFig. 1.

The means whereby individual labels or other elements I! aresuccessively removed from the upper end of the supply stack andtransferred therefrom for adhesive application to the articles for whichthe labels or other elements are designed may be of the suction operatedor any other suitable type. The said transfer means, in its illustratedform, consists of a carriage 2B slidably mounted upon a fixed guide rail29 suitably supported on the frame I5 as shown in Fig. 1. Suitable meansof conventional type is provided for slidably reciprocating the carriage28 on the rail 29 and, as shown, comprises an arm 30 fixed on the shaft25 and having its free end pivotally connected with a coupling rod 3|which in turn is yieldingly and pivotally connected at 32 with thecarriage 28. It will be understood that the shaft 25 is rocked on itsaxis in properly timed relation with the other elements of the machinein any convenient and well-known manner.

In the operation of the machine, the carriage 28 with its associatedelements, to be more fully set forth hereinafter, is reciprocated on therail 29 many times during an operative period and at opposite ends ofits reciprocating movements engages adjustable abutments 33 suitablymounted on the frame I5. Obviously repeated reciprocation of saidcarriage 28 lengthwise of the rail 29 results in wear of the parts; thelatter finally disturbs the co-operative association of the parts anddevelops conditions whereby the efficiency and operative accuracy of themachine is reduced.

To overcome these disadvantages without requiring replacement of partswith consequent expense and loss of time, the machine is provided withnovel means whereby the aforesaid wear may be compensated and theeffects thereof neutralized in a simple and efficient manner. Asillustrated in Fig. 4, the rail 29 is accordingly provided along itsopposite longitudinal edges with guide-members 34 formed with V-shapedor equivalent guide grooves 35 into the upper of which is slidablyfitted an upper slide member 39. The latter is mounted in fixed positionupon the carriage 2 3 in any suitable manner and, as shown, is providedat its opposite ends with lugs 31 for the accommodation of screws or thelike 38, whereby said upper slide member 35 is fastened in place onconvenient parts of said carriage 28. A similar lower slide member 39 isslidably fitted into the lower guide groove 35 of the rail 29 and isadjustably mounted on the carriage 28 in any convenient manner; forinstance, as shown in Fig. 2, the lower slide member 39 may include lugs40 located at its opposite ends and provided with slots 41 for theaccommodation of screws 42 which are threaded into contiguous parts ofthe carriage 28. The latter further carries set screws 43 which bearagainst the lower slide member 39 and are fixed against unintentionalmovement by means of lock nuts 44. It will be understood, as shown byway of example in the drawings, that the slide members 33 and 39, inevery instance, are shaped in cross-section to properly and slidably fitthe guide grooves 35.

With this arrangement the lower slide member 39 may be adjustedrelatively to its associated guide groove 35 to a set position on thecarriage 28 for proper cooperation with the upper slide member 38 toslidably mount said carriage 23 most efiiciently on the rail 29. playresulting from wear disturb the efiiciency of the mounting of thecarriage 28 on the rail 29, this may readily be corrected by properlyadjusting the lower slide member 39 relatively to the associated guidegroove 35 to a new set position on said carriage 28. The aforesaidadjustment of the lower slide member 39 may be easily and accuratelyeffected by loosening the screws 42 and the lock nuts 44 and thenmanipulating the set screws 43. The latter by bearing against the slidemember 39 will cause the latter to move relatively to the screws 42 intothe lower groove 35 of the rail 29, such movement being possible becauseof the slots 4|; when the desired adjustment has been accomplished, thescrews 42 are tightened to secure the member 39 in its new set positionand the lock nuts 44 are screwed up to prevent unintentional dislocationof the set screws 43.

In addition to the parts so far described, the machine includes means onthe carriage 28 and operated at the opposite ends of the reciprocatorymovements thereof to respectively pick up successive labels or otherelements I! from the supply stack and to apply them to the articles forwhich said labels or other elements I! are designed. As shown in thedrawings, the aforesaid means consists of a carrier or member 45slidably mounted on the carriage 28 for vertical reciprocation thereonand provided at its lower end with a yoke 43 as shown in Fig. 8. Asuction head 4'! is mounted upon the yoke 45 in any convenient mannerand is connected with a suitable source of suction, for instance, bymeans of a flexible tube 48; as the suction head and suction producingmeans may be of any conventional If looseness and type and per se formno part of the instant invention, it has been deemed unnecessary toillustrate the same in detail.

As the vertical reciprocation of the carrier 45 and its associatedelements relatively to the carriage 28 results in wear of the parts overa period of use which may result in disturbing the accuracy of operationof the machine, novel means is provided for compensating such wear in asimple and efficient manner and without requiring repeated replacementof parts. As shown in Figs. 3 and 5, the carrier or member 45 isaccordingly provided along its opposite vertical edges with guidegrooves 49 of V-shape or equivalent form in cross-section, into one ofwhich is slidably fitted a slide member 59. The latter is mounted inrelatively fixed position on the carriage 28 in any suitable manner, asas shown, is provided at its opposite ends with lugs 5| for theaccommodation of screws 52 whereby said slide member 59 is fastened inplace on convenient parts of said carriage 28. A similar slide member 53is slidably fitted into the opposite guide groove 49 of the carrier ormember 45 and is adjustably mounted on the carriage 28 in any convenientmanner; for instance, as shown in Fig. 2, the slide member 53 mayinclude lugs 54 located at its opposite ends and provided with slots 55for the accommodation of screws 56 threaded into contiguous portions ofthe carriage 28. The latter further is provided with lugs 51 havingthreaded apertures for the screwthreaded reception of set screws 58which bear against the outer edge of the slide member 53 and are fixedagainst unintentional movement by means of lock nuts 59. It will beunderstood, as shown by way of example in Figs. 3 and 5, that the slidemembers 59 and 53 are shaped in cross-section to properly and slidablyfit the guide grooves 49.

With the aforesaid arrangement the slide member 53 may be adjustedrelatively to the associated guide groove 49 to a set position on thecarriage 28 for proper co-operation with the slide member 50 to slidablyguide and accurately maintain the carrier or member 48 in its intendedpath of reciprocation without objectionable vibration. If looseness andplay resulting from wear develop after a period of use to disturb theefficiency of the slidable mounting of the carrier or member 48 on theslide members 59 and 53, this may be readily corrected by properlyadjusting the slide member 53 to a new set position on said carriage 28.The aforesaid adjustment of the slide member 53 may be easily andaccurately eflected by loosening the screws 56 and lock nuts 59 and thenmanipulating the set screws 58. The latter by bearing against the outeredge of the slide member 53 will shift the latter relatively to thescrews 55 into the associated guide groove 49 of the carrier or member45, such shifting being possible because of the slots 55; when thedesired adjustment has been accomplished, the screws 56 are tightened tosecure the slide member 53 in its new set position and the lock nuts 59are screwed up to prevent unintentional displacement of the set screws58.

The operations of resetting the slide member 39 to neutralizedisturbances in the slidable mounting of the carriage 28 on the rail 29,and the slide member 53 to compensate disturbances in the slidablemounting of the carrier or member 45 on the carriage 28, may be repeatedas often as required. In this way the carriage 28 and the carrier ormember 45 may be accurately maintained in their respective paths ofreciprocation, and objectionable looseness and vibration in therespective parts maybe definitely avoided without requiring frequentreplacement of said parts.

As shown in the drawings, the machine includes means for maintaining thecarrier 45 against downward movement on the carriage 28 throughoutpredetermined portions of its reciprocative movements to therebyposition the suction head 41 and a label or other element ll car riedthereby, in proper relation to the adhesive applying roll 21 to receivean application of ad-' hesive therefrom as will appear more fullyhereinafter; provision is also made for effecting vertical reciprocationof the carrier 65 relatively to the carriage 28 at the proper points inan operative cycle of the machine to effect the desired operative steps.

The illustrated machine accordingly is provided with a stationarysupporting rail 60 mounted in place in any suitable manner for instancein parallel relation to and at a predetermined distance above the rail29 as shown in Figs. 1 and 4. The rail 68 is formed in its upper edgewith recesses (H and 62 located in predetermined relation respectivelyto the stack of labels or other elements H in the container l6 and tothe applying station at which the labels or other elements [7 areapplied to articles A for which they are designed; the articles Areferred to are supported in position for adhesively receiving thelabels or other elements I! in any convenient manner at said applyingstation. A movable supporting rail 63 is located in spaced parallelismwith the stationary supporting rail so, and as shown in Figs. 4 and 8may be provided with a flange 64 along its free edge, the upper surfaceof said flange 64 being in the same horizontal plane with the uppersurface of the rail 69. In the illustrated arrangement the rails 69 and63 are located upon opposite sides of the path of reciprocation of theupper portion of the carrier 45, it being understood that the movablerail 63 is of sufiicient length to extend throughout the horizontal pathof movement of the suction head 41 and associated elements in theperformance of their operative functions. The movable supporting rail 63is carried by one or more arms 65 fixed upon a shaft 66 suitably mountedin the machine for instance as shown in Fig. 8, said shaft 66 having alever 67 fastened thereon and operatively connected in any convenientmanner with conventional mechanism operating in properly timed relationwith the other elements of the machine to rock said shaft 66 and therebyraise and lower said rail 63 to correspondingly operate the carrier 3'?and suction head d? on the carriage 23. For co-operation with the rails59 and 63, the carrier 45 is provided with rollers 68 and 68 rotatablycarried by a stud to project ing through a bearing lug H projectingupwardly from the upper end of the carrier 25 as illustrated in Figs. 2,4, and 8; the stud may be in the nature of a bolt provided with a head wand a nut 18 The arrangement is such that the roller 68 travels inrolling engagement with the upper or traction surface of the stationarysupporting rail 60 while at the same time the roller 69 travels inrolling engagement with the upper or traction surface of the flange M ofthe movable supporting rail 53. A spring 45 may be provided fordeveloping an elastic tension on the carrier 45 to thereby yieldinglymaintain the rollers 68 and 69 in rolling engagement with the respectiverails 60 and 63.

To neutralize the effects of wear and to enable the active surface ofthe suction head 41 to be maintained at and adjusted to the mostefficient level relatively to the adhesive applying roll2l, the stud 10passes through a sleeve or bushing 12 in eccentric relation thereto. Thebushing 12 is fixed upon the stud 10 in any convenient manner and isrotatably mounted in the bearing lug H as shown in Figs. 4 and 5, a setscrew 13 serving to fix said bushing 12 in its adjusted position.Obviously if the bushing 12 is rotated in the lug II, the stud 10 willbe adjusted to different positions relatively to the supporting rails 60and 63 and will adjust the rollers 68 and 69 correspondingly tocompensate for wear of the parts or for purposes of adjusting the levelof the active face of the suction head 41. The aforesaid adjustment alsoenables the latter to be set so that the labels or other elementscarried by the suction head 41 regardless of the thickness of thematerial, will always be positioned for proper tangential engagementwith the adhesive roller 21 to receive an application of adhesivetherefrom. The rotatable adjustment of the bushing 12 may be effected inany suitable manner as for instance by loosening the nut Ill and thenrotating the stud ll] on its axis by means of the head Hi thismanipulation of the stud 10 is communicated to the bushing 12 as will beapparent.

The machine may also be provided with means for controlling theapplication of adhesive to the labels or other elements I! in apredetermined manner, as exemplified by restricting the application ofadhesive to only certain parts of said labels or other elements H andpreventing adhesive from being applied to other parts of said labels orother elements IT. For instance, in many types of label application itis desirable to apply strips of adhesive a along opposite edges of asurface of a label I! and to leave the intermediate portions b of saidlabel I! free from and uncoated with such adhesive as shown in Fig. 13;in other cases, the labels may be coated with adhesive by beginning theapplication thereof at an intermediate point of the surface of a labelll or its equivalent, and continuing said application to an edge thereofas illustrated by the right hand strip a in Fig. 13. To obtain thisresult, a cam member 14 is mounted on the fixed supporting rail 60 inpredetermined relation to the adhesive applying roll 21. In thepreferred arrangement the cam member 14 is adjustably mounted on therail 69 and for this purpose may be formed with a slot 15 for theaccommodation of a set screw 16 threaded into an aperture II with whichthe rail 60 is provided. To enable the cam member 14 to be mounted atdifferent points along the rail Gil, the latter may include a pluralityof apertures ll each arranged to receive the screw 16 or its equivalent.With this arrangement it is also possible to con-currently mount anumber of cam members M at different points of the rail Ell to obtainvarious types of adhesive application to a label or other element H.

In practice, assuming the machine is used for adhesively applyingsuccessive labels 57 to suecessive articles A suitably supported at theapplying station of the machine, and that in Fig. l the parts are shownin position at the socalled label applying station of the machinesubsequent to the application of a label I? to an article A, the shaft66 will be rocked in properly timed relation with the other elements ofthe machine, by the lever 61 and its operating mechanism in a directionto swing the arm or arms 65 and with them the movable supporting rail 63in an upward direction. A lifting action will thus be exerted on theroller 69 to thereby raise the carrier 45 and with it the suction head41 on the carriage 28 to a position above that shown in Fig. 1 so thatthe active face of the suction head 47 is at a level higher than that ofthe adhesive applying roll 21.

As the shaft is now rocked on its axis, the lever will be swung to theright in Fig. l and by means of the coupling rod 3| will slidably pullthe carriage 28 in the same direction lengthwise of the rail 29 untilsaid carriage 28 engages the right hand abutment 33, at which time thesuction head 41 will be located above and in registry with the upper endof the stack of labels I! in the container l6. During these operativesteps,

the cam 24 partakes of the rocking movement of the shaft 25 and byacting on the roller 23 will swing the bell crank lever 2| in adirection to raise the feeler I8 away from the upper end of the supplystack of labels I! to an inoperative position in which it does notinterfere with the subsequent actuation of the suction head 41 in theremoval of a terminal label I! from said supply stack.

As the carriage 28 is thus slidably moved to the right on the guide rail29, the roller 69 will travel lengthwise of the elevated supporting rail53 to thereby maintain the carrier in a raised position on said carriage28, in which raised position the active face of the suction head 41 a isat a higher level than the adhesive applying roller 2? and accordinglydoes not contact therewith. At the end of this sliding movement towardthe right, the roller 68 will be above and in registry with the recess6| of the stationary supporting rail 60, with the roller 69 still inrolling engagement with the elevated supporting rail 63. At the propermoment the shaft 65 will be rocked in a direction to swing the arm orarms 65 downwardly to thereby lower the supporting rail 63 and with itthe carrier 45 on the carriage 28. The roller 68 thereby movesdownwardly into the recess 6| of the rail 60 and the suction head 41moves into engagement with the upper end of the supply stack of labelsI1.

In proper operative synchronism with these operations suction will beautomatically developed in the suction head 41 in any conventionalmanner and will cause the terminal label I! in the supply stack toadhere to the active face of said suction head 41 in the Well-known way.

When the terminal label I! has thus been picked up, the shaft 66 and arm65 will be rocked in a direction to elevate the supporting rail 63 androller 69 to thereby raise the carrier 45 and. suction head 41 with thepicked up label I! and to concurrently lift the roller out of the recess6| to the level of the traction surface of the stationary supportingrail 60. At this stage, the mechanism will be operated to slidably shiftthe carriage 28 along the guide rail 29 toward the left in Fig. l, theroller 68 meanwhile traversing the fixed supporting rail to therebymaintain the carrier 45 and its associated parts in the aforesaid raisedposition as the carriage 28 travels along the guide rail 29; it will beunderstood that the supporting rail 63 is moved downwardly and away fromthe roller 59 at the beginning of the aforesaid operations in thewellknown way.

In this position of the parts, the lower surface of the label I! carriedby the suction head 41 is at the level of the adhesive applying roll 21and will be caused to pass over and in tangential surface contacttherewith as the carriage 28 travels to the left, whereby said lowersurface of said label I! will receive a coating of adhesive from saidroll 21. If a cam member 14 is in place on the supporting rail 60, forinstance, as illustrated in Fig, l, the roller 68 will pass over saidcam member 14 and accordingly will lift and lower the suction head 41and the label I! carried thereby, whereby the intermediate portion bthereof will be prevented from contacting with adhesive applying roll21, and strips of adhesive a will be applied only to the opposite edgeportions of said label IT as shown in Fig. 13; in other cases, anadhesive receiving relation will be established with the applying roll21 beginning at a predetermined intermediate point of the surface of thelabel [1 or its equivalent, and continued to the rear edge thereof asillustrated by the right hand strip a in Fig. 13. In such case theapplication of adhesive to the label I! or equivalent element beginsafter the leading edge of said label I! or equivalent element has passedbeyond the axis of the adhesive applying roll 21 in the direction inwhich said label I! or equivalent element is being carriedby the suctionhead 4? or equivalent transfer means.

As its travel to the left in Fig. 1 continues, the carriage 23 willfinally engage the left hand abutment 33 and come to rest. At thisstage, the roller 68 is located above and in registry with the recess 62of the stationary supporting rail and the suction head 4! with the labelH carried thereby is in label applying relation to the particulararticle A located in the machine at the time. In proper operativesynchonism with the other parts of the machine, the shaft 65 is rockedin a direction to swing the arm 65 and supporting rail 63 downwardly andslidably lower the carrier 45 on the carriage 28 to thereby cause thesuction head 4! to bring the label I! carried thereby into contact withthe article A, it being understood when this initial application hasbeen completed that the suction in the suction head 41 is automaticallycut off. As a new operative cycle is now started, the suction head 4'!is raised and the particular label I! remains in adhesive connectionwith the article A. The adhesive application of said label I! to saidarticle A may be completed by means of a conventional pressure member 18operated in any well-known manner in proper timing with the associatedmechanism. When the application of the label has been completed, thelabeled article A is removed from the machine and replaced with anotherarticle A after which the aforesaid operations are repeated.

During an operative period, the slide members 36 and 39 in co-operationwith the guide grooves 35 maintain the carriage 28 in its intended pathof reciprocation without harmful vibration, and the slide members 50 and53 in co-operation with the guide grooves 49 correspondingly maintainthe carrier 45 in its vertical reciprocative path on the carriage 28 inan efficient and reliable manner. As previously explained herein,disturbances of these conditions resulting for instance from wear of theparts, may be corrected b periodical adjustment of the slide members 39and 53 respectively.

In Figs. 9, 10, and 11, I have shown another form of the means forcontrolling the application of adhesive to the labels or other articlesin a manner to apply the adhesive only to certain parts of the labels orother articles, and to avoid such application to other parts thereof. Toexemplify this last-named controlling means and its operation, I haveillustrated it in a form adapted for applying adhesive to an element orblank ll intended to be adhesively attached to an article such as apaper drinking cup and ineluding handle sections 1) foldably connectedalong score lines 11 with a body section a which, as shown, may beprovided with transverse ears or projections a extending in oppositedirections from said body section a at opposite ends there of. In itsnormal condition, the element or blank I! is fiat and in this conditionis adhesively applied to a paper drinking cup or equivalent article in amanner to leave the handle sections b free to be bent toward each otheron the score lines I) so as to project outwardly fro-m said cup or otherarticle to constitute a handle therefor. In practice, a supply ofelements or blanks I! in fiat condition may be located in the form of asupply stack in a container such as the container l6 of Fig. 1. Duringan operative cycle of the machine, which may be constructed and operatedin the same way as the machine shown in Fig. 1, individual blanks Il areremoved from the upper end of the supply stack and transferred to theapplying station of the machine for adhesive application to the cups orother articles for which said blanks are designed. During their travelfrom the supply stack to the applying station, the blanks l'l receive anapplication of adhesive (1 controlled in such a way that only a surfaceof the body a and projection a receive the adhesive coating while thecorresponding surfaces of the handle sections 1) receive no adhesive asshown in Fig. 12; the application of adhesive a may be effected by meansof an adhesive applying roll 21 corresponding to the roll 21 of Fig. 1.

The aforesaid controlling means, as shown in Figs. 9, 10, and 11, maycomprise cam members I l each having one end curved or otherwiseprojected downwardly as illustrated at la The cam members M may be fixedin place in the machine in any suitable Way and, as shown, are providedwith upright longitudinal flanges 19 attached to brackets or arms 89which themselves are mounted in the frame I5 in any convenient manner.In any case, the cam members I i are located in parallel relation toeach other at a predetermined distance apart in co-operativerelation tothe adhesive applying roll 2'1 and extending beyond the same asillustrated by way of example in Figs. 9, 1i), and 11. The suction headH corresponding to the suction head ll of Figs. 1 and 8 is dimensionedand shaped in dependence upon the character of the blank or element lland is mounted in the machine and operated therein in the same way as inFig. 1; thus in the instant case the suction head W corresponds in widthto the width of the body section a of the blank or other article ll andis of a length substantially corresponding to the length of said bodysection a as shown by broken lines in Fig. 11.

With the described arrangement when a blank I! has been picked up fromthe supply stack by the suction head 41*, the body section a will bedrawn and held against the active surface thereof by the suction in saidsuction head M while the handle sectionsb' of said blank ll will projectlaterally beyond the suction head 41* in opposite directions; ifnecessary or desired, provision may be made on the suction head 4'! toprovide backings for the projections a of said blank ll to maintain thesame in position during the application of adhesive thereto. In anycase, as the suction head 41* carrying a blank ll approaches theadhesive applying roll 21 the handle sections 1) will ride up on thecurved or equivalent ends 14* and along the cam members 14 and willthereby be swung upwardly on the score lines b as illustrated in Figs.10 and .11. In this position the handle sections b are maintained out ofcontact with the adhesive applying roll 2'! and are retained in thisposition until said sections b pass from the cam members I i at pointsbeyond the adhesive applying roll 2?. Meanwhile, the common bottomsurfaces of the body section a and projections a have passed inprogressive tangential engagement with said applying roll 21 and havereceived a coating 0, of adhesive therefrom as shown in Fig. 12. As theoperation of the machine continues, the blank ll will be deposited uponthe cup or other article at the applying station to adhesively connectthe body section a and projections a therewith and leave the handlesections b" free to be bent outwardly at will on the score lines b toprovide a handle for said cup or other article. Obviously the blank llor its equivalent may be designed for adhesive connection with otherarticles to serve otherwise than as a handle therefor, in which case thecontrolling means will be arranged to effect a properly co-operatingapplication of adhesive. 7 l?he means for controlling the application ofadhesive in the form of strips to a label or other element avoids thenecessity for expensive strip gumming rolls or other correspondinglyexpensive special devices. The described controlling means isparticularly desirable for applying strips of adhesive or other patternsthereof on 1abels or other elements which are made of heavy materials orof such thickness as to be incapable of being temporarily distorted outof their normal surface planes as is done in certain types of patterngluing. The controlling means further provides a simple and eificientarrangement for bringing about the application of adhesive only tocertain parts of a label or other element and leaving other partsthereof free of adhesive for any predetermined purpose. The controllingmeans in all of its forms may readily be incorporated in existingmachines.

The novel means for compensating wear of parts require no skill in theirmanipulation and are of maximum efficiency in action and definitelyinsure accurate application of labels to the articles at all timeswithout necessitating frequent replacement of parts.

Various changes in the specific forms shown and described may be madewithin the scope of the claims without departing from the spirit of theinvention.
